RFR: 8325972: Add -x to bash for building with LOG=debug

Thu Feb 15 15:13:14 UTC 2024

I don't understand why I have never thought of this before. If we add `-x` to the set of bash arguments when running with LOG=debug, we get output of *all* shell commands that make is running, even those for $(shell).

This makes it soooo much easier to understand what is actually happening in the makefile! (To the point where we could actually consider moving other stuff away from the debug level.)
